racks.
FIG. 10 to FIG. 12 are exemplary views of a light emitting device
according to an eighth embodiment of the present disclosure. A
light emitting device 800 according to the eighth embodiment
includes a device housing 810 and a sterilization module 820.
Referring to FIG. 10, the sterilization module 820 includes a
module housing 821, a substrate 121, and a light source 122.
The module housing 821 has an inner space defined by at least an
upper surface and side surfaces. The substrate 121 and the light
source 122 are disposed in the inner space of the module housing
821. Further, the module housing 821 is formed on an upper surface
thereof with a UV light outlet 822 having a through-hole structure.
The UV light outlet 822 is a path through which UV light for
sterilization emitted from the light source 122 is discharged

applied to the hanging portion 812 is removed, the hanging portion
812 is pushed into the interior space of the device housing 810 by
the elastic component connected to one end of the hanging portion
812, as shown in FIG. 11. Alternatively, the hanging portion 812 in
its entirety may be formed of an elastic material. Various and
different designs and configurations are available for the hanging
portion 812.
When the sterilization module 820 is inserted into the device
housing 810, the hanging portion 812 is pushed toward the inner
side surface of the device housing 810 and then presses the
sterilization module 820 by elastic force, as shown in FIG. 12.
Accordingly, the sterilization module 820 is secured in a state of
being inserted into the device housing 810 by the hanging portion
812, as shown in FIG. 12. Here, the sterilization module 820 is
inserted into the device housing 810 such that the upper surface of
the sterilization module 820 having the UV light outlet 822 formed
thereon is directed toward the lower portion of the device housing
810. Thus, UV light for sterilization emitted through the UV light
outlet 822 of the sterilization module 820 is discharged through
the open lower portion of the device housing 810 and reaches the
skin.
In the light emitting device 800 according to this embodiment, the
sterilization module 820 is detachably coupled to the device
housing 810. When there is a malfunction in the sterilization
module 820 integrally formed with the device housing 810, the light
emitting device 800 must be replaced. However, since the light
emitting device 800 according to this embodiment allows the
sterilization module 820 to be detachably coupled to the device
housing 810, the light emitting device 800 can be used by replacing
the sterilization module 820 with a normal sterilization
module.
FIG. 13 and FIG. 14 are exemplary views of a light emitting device
according to a ninth embodiment of the present disclosure. A light
emitting device 900 includes a device housing 810 and a
sterilization module 820. Referring to FIG. 13, the device housing
810 includes a sterilization module insertion portion 811 and a
hanging portion 910. The sterilization module insertion portion 811
is formed on an upper surface of the device housing 810 and has a
penetration structure.
The hanging portion 910 protrudes from an inner side surface of the
device housing 810. In addition, the hanging portion 910 is formed
to have elasticity. The hanging portion 910 may have the same
structure as the hanging portion 812 of the light emitting device
800 (see FIG. 11 and FIG. 12) according to the eighth
embodiment.
According to this embodiment, the hanging portion 910 is composed
of a plurality of layers. Referring to FIG. 13, the hanging portion
910 is composed of three layers. For convenience of description,
the hanging portion 910 includes a first hanging portion 911, a
second hanging portion 912, and a third hanging portion 913. The
number of layers constituting the hanging portion 910 may be
changed, as needed.
Referring to FIG. 14, the sterilization module 820 is inserted into
the device housing 810 through the sterilization module insertion
portion 811. Here, the sterilization module 820 may be inserted
into the device housing 810 to reach a preset location therein.
Referring to FIG. 14, the sterilization module 820 is inserted into
the device housing 810 such that an upper surface of the
sterilization module 820 contacts an upper surface of the first
hanging portion 911.
The second hanging portion 912 and the third hanging portion 913
presses the sterilization module 820 to secure the sterilization
module 820 inside the device housing 810. In addition, the first
hanging portion 911 acts as a buttress preventing the sterilization
module 820 from moving downwards.
Such a light emitting device 900 can adjust a securing location of
the sterilization module 820 in the device housing 810 through the
hanging portion 910 composed of a plurality of layers. That is, the
light emitting device 900 can adjust a distance between UV light
for sterilization and the skin.
In some embodiments, a region irradiated with UV light for
sterilization increases as a distance between the skin and the
sterilization module 820 increases. In addition, the region
irradiated with UV light for sterilization decreases as the
distance between the skin and the sterilization module 820
decreases. Accordingly, the light emitting device 900 allows the
entirety of an infected region of the skin to be irradiated with
the UV light for sterilization by adjusting the distance between
the sterilization module 820 and the skin. Further, the light
emitting device 900 may emit UV light for sterilization mainly
toward the infected region of the skin by adjusting the distance
between the sterilization module 820 and the skin. Here, a UV
blocking material may be applied to normal skin placed within an
irradiation range of UV light for sterilization to protect the
normal skin from the UV light for sterilization. In addition, the
light emitting device 900 may prevent the normal skin from being
irradiated with UV light for sterilization while allowing the UV
light for sterilization to reach only the infected region of the
skin by adjusting the distance between the sterilization module 820
and the skin. Here, when only the infected region of the skin is
irradiated with the UV light for sterilization, applying the UV
blocking material to the normal skin may be avoided.
FIG. 15 to FIG. 17 are exemplary views of a light emitting device
according to a tenth embodiment of the present disclosure. A light
emitting device 1000 according to the tenth embodiment includes a
device housing 1010 and a sterilization module 1020.
Referring to FIG. 15, the sterilization module 1020 includes a
module housing 1021, a substrate 121, and a light source 122. The
substrate 121 and the light source 122 are disposed inside the
module housing 1021. The module housing 1021 has a thread formed on
an outer surface thereof, as shown in FIG. 15.
Referring to FIG. 16, the device housing 1010 is formed with a
sterilization module insertion portion 811. The sterilization
module insertion portion 811 has a through-hole structure
penetrating an upper surface of the device housing 1010. In
addition, a thread is formed on an inner surface of the
sterilization module insertion portion 811.
Referring to FIG. 17, the sterilization module 1020 is inserted
into the device housing 1010 through the sterilization module
insertion portion 811. Here, the outer surface of the module
housing 1021 engages with the inner surface of the device housing
1010.
In the light emitting device 1000, the sterilization module 1020 is
coupled to the device housing 1010 through screwed type coupling
and is secured in a state of being inserted into the device housing
1010.
In addition, since the sterilization module 1020 is coupled to the
device housing 1010 through screwed type coupling, the light
emitting device 1000 can adjust the securing location of the
sterilization module 1020. That is, the light emitting device 1000
can adjust the distance between the sterilization module 1020 and
the skin.
A region irradiated with UV light for sterilization increases as a
distance between the skin and the sterilization module 1020
increases and the region decreases as the distance between the skin
and the sterilization module 1020 decreases. Accordingly, the light
emitting device 1000 can adjust a region to be irradiated with the
UV light for sterilization through adjustment of a coupling depth
of the sterilization module 1020 to the device housing 1010. For
example, the light emitting device 1000 allows the entirety of the
infected region of the skin to be irradiated with UV light for
sterilization by adjusting the coupling depth of the sterilization
module 1020 to the device housing 1010. In addition, the light
emitting device 1000 may emit UV light for sterilization mainly
toward the infected region of the skin by adjusting the distance
between the sterilization module 1020 and the skin. Here, a UV
blocking material may be applied to normal skin placed within an
irradiation range of UV light for sterilization to protect the
normal skin from the UV light for sterilization. In addition, the
light emitting device 1000 may prevent the normal skin from being
irradiated with UV light for sterilization while allowing the UV
light for sterilization to reach only the infected region of the
skin by adjusting the distance between the sterilization module
1020 and the skin. Here, when only the infected region of the skin
is irradiated with the UV light for sterilization, it is not
necessary to apply the UV blocking material to the normal skin.

Further, the module housing 821 is formed on an upper surface
thereof with a UV light outlet (not shown) having a through-hole
structure. The substrate and the light source are disposed inside
the module housing 821 such that UV light for sterilization is
directed toward the UV light outlet.
The sterilization module 820 is disposed on the device housing 210.
Here, the sterilization module 820 is disposed on the device
housing 210 such that the UV light outlet of the module housing 821
faces the upper surface of the device housing 210. Accordingly, UV
light for sterilization emitted from the sterilization module 820
reaches the skin through the upper surface of the device housing
210.
The bonding member 1110 is formed between the sterilization module
820 and the device housing 210. The bonding member 1110 improves
bonding strength between the sterilization module 820 and the
device housing 210 to prevent the sterilization module 820 from
being separated from the device housing 210.

sterilization module 1220 emits UV light for sterilization outwards
through the upper surface portion 1223.
Referring to FIG. 21, the sterilization module 1220 is disposed on
an upper surface of the device housing 1210. Here, the upper
surface portion 1223 of the module housing 1221 is inserted into
the sterilization module securing portion 1211 of the device
housing 1210. Since the sterilization module securing portion 1211
is formed to have elasticity, the upper surface portion 1223 of the
module housing 1221 can be easily inserted.
As such, the light emitting device 1200 can secure the
sterilization module 1220 to the device housing 1210 by fitting the
upper surface portion 1223 of the module housing 1221 into the
sterilization module securing portion 1211 of the device housing

may be provided as an independent component with respect to the
device housing 210 and the band portion 1310, or may be provided in
the form of being previously attached to the lower surface of the
device housing 210.
Since the band portion 1310 is flexibly attached to the skin, the
light emitting device 1300 according to this embodiment can be
easily attached to a curved region of the skin and can maintain an
attached state even when the attached region of the skin is
moved.
The device housing 210 is secured to the skin. In addition, the

surface of the device housing 110 via a bonding material.
In the light emitting device 1500, the lower surface of the device
housing 110 to be secured to the skin is hard and has a small area.
Since the hard lower surface of the device housing 110 has a small
width, it is possible to suppress widening of a gap between the
lower surface of the device housing 110 and the skin due to
movement of the skin. Even when the gap between the lower surface
of the device housing 110 and the skin is widened, a fraction of
the band portion 1310 separated from the skin by the device housing
110 is limited due to the small width of the lower surface of the
device housing 110. Accordingly, the light emitting device 1500
according to this embodiment is suitable for a region of the skin
